Memory Size

[asdfjkl]

I wonder whether there is a bug in the machine implementation (or maybe I am confusing something).

• the instruction pointer points to (absolute) offsets, i.e. for next() and prev() it is increased by sizeof(int32_t). Since it is a pointer of type int32, the pointer is internally increased by sizeof(int32_t) * sizeof(int32_t).
• memory is allocated by memory(new int32_t[memsize]), but memsize itself is initialized as memsize(10001024sizeof(int32_t)),

Therefore I think you are using sizeof(int32_t) more memory than actually required. I think there are two ways to resolve this:

• a) decrease memory size and access memory contents by memory[ip/4]
• b) decrease memory size and access memory contents by manual computation of the offset of the allocated memory unsigned int* offset = (unsigned int*) ((unsigned char *) memory + ip);
